There are several types of nanoscale sensors, each designed for specific applications:
Chemical Sensors: These sensors detect specific chemical substances through interactions with nanoscale materials that change their properties, such as electrical conductance or optical absorption. Biosensors: These sensors use biological molecules, such as enzymes or antibodies, attached to nanomaterials to detect specific biological substances like glucose or pathogens. Physical Sensors: These sensors measure physical changes, such as temperature, pressure, or mechanical stress, using nanomaterials that respond to these changes with high sensitivity. Optical Sensors: These sensors use changes in optical properties, such as fluorescence or plasmon resonance, of nanomaterials to detect the presence of target molecules.
